You don´t even need to create outlets for your navBar and tabBar to achieve this. Create an outlet to your imageView as you have done.

@IBOutlet var FullPhoto: UIImageView!

And then in your viewDidLoad

let tapRecognizer = UITapGestureRecognizer(target: self, action: "tapImage")
FullPhoto.addGestureRecognizer(tapRecognizer)
FullPhoto.userInteractionEnabled = true

And then create the tap method and check for the navigationController and the tabBarController.

func tapImage(){
     if navigationController?.navigationBar.hidden == false && tabBarController?.tabBar.hidden == false{
         navigationController?.navigationBar.hidden = true
         tabBarController?.tabBar.hidden = true
     }
     else{
         navigationController?.navigationBar.hidden = false
         tabBarController?.tabBar.hidden = false
     }
}
